*lighter and better materials in the shell. cut down on a little bit of the bulk too *Laces are not so excessively long and the clips are replaced with snaps to prevent lace dangle 100% *(my favorite) addition of the new Poron foot beds, before there was no foot bed other than the liner *Intuition liners are better quality and are absent of the skanky female silhouette graphics that are not the most family friendly ;) *Interior ankle cuff and laces is removable and better quality too

i looked into the pb floids, but i don't like having to worry about the hiking boot style lace loops that have to be looped around in lacing... plus i think i like the stiffer d2 anyway. just my opinion ;) try them out in the store... or better yet on/in the water
